parameters valued at zero are not passed to the parameter.

if I take out the '' + for scope.start, then zero is NOT inserted into the URL of the POST - you don't get
POST /noogle/find_result/20/0?format=json

you get

POST/noogle/find_result/20?format=json

basically parameters of 0 are falsy and not inserted into URLs.

I ran into this error as well... My team thought it would be a good idea to have our REST call Id's be zero indexed, but found that the first element (id 0) would simply result in the REST call without id.
